Communicable Diseases Surveillance - Tables

This report published in Communicable Diseases Intelligence Volume 23, No 11, 28 October 1999 contains an analysis and tables of monthly notifiable diseases and laboratory data, and quarterly surveillance reports.

There were 5,374 notifications to the National Notifiable Diseases Surveillance System (NNDSS) in the four week period, 15 September to 12 October 1999 (Tables 1 and 2). The numbers of reports for selected diseases have been compared with historical data for corresponding periods in the previous three years (Figure 1).

There were 4,310 reports received by the Virology and Serology Laboratory Reporting Scheme (LabVISE) in the four week period, 9 September to 6 October 1999 (Tables 3 and 4).

The Australian Sentinel Practice Research Network (ASPREN) data for weeks 37 to 40, ending 10 October 1999, are included in this issue of CDI (Table 5).

8. NT, Qld, SA and Vic: includes gonococcal neonatal ophthalmia.
9. Nationally reportable from August 1998.
10. Unspecified numbers should be interpreted with some caution as the magnitude may be a reflection of the numbers of testings being carried out.
11. Includes hepatitis D and E.

1. The historical data are the averages of the number of notifications in the corresponding 4 week periods of the last 3 years and the 2 week periods immediately preceding and following those.

Top of pageTable 4. Virology and serology laboratory reports by contributing laboratories for the reporting period 9 September to 6 October 1999

The NNDSS is conducted under the auspices of the Communicable Diseases Network Australia New Zealand. The system coordinates the national surveillance of more than 40 communicable diseases or disease groups endorsed by the National Health and Medical Research Council (NHMRC). Notifications of these diseases are made to State and Territory health authorities under the provisions of their respective public health legislation. De-identified core unit data are supplied fortnightly for collation, analysis and dissemination. For further information, see Commun Dis Intell 1999;23:58.

LabVISE is a sentinel reporting scheme. Twenty-one laboratories contribute data on the laboratory identification of viruses and other organisms. Data are collated and published in Communicable Diseases Intelligence every four weeks. These data should be interpreted with caution as the number and type of reports received is subject to a number of biases. For further information, see Commun Dis Intell 1999;23:58.

ASPREN currently comprises about 100 general practitioners from throughout the country. Up to 9,000 consultations are reported each week, with special attention to 12 conditions chosen for sentinel surveillance in 1999. CDI reports the consultation rates for seven of these. For further information, including case definitions, see Commun Dis Intell 1999;23:55-56.
